The wife went to start the 2003 (110K miles) Escalade 2WD with tow package and the battery was dead. We have had it about 6 months with NO issues and it is an awesome vehicle. It was driven yesterday and has been setting as much as five days at a time during the snow and the battery stayed up fine.
I put the B&D charger on it and the amperage jumped around at first then went to charging the max charger setting. Once the charger started to taper then the amperage again started varying over a 6 amp range all the way down to about 1 amp.
There was faint clicking under the hood and I though it was the B&D charger changing modes but it was every minute or two.
After removing the neg battery cable the clicking under the hood (not yet pin pointed the source for sure) which is not very loud at at all.
When I screwed a post terminal into the battery where I removed the neg cable and reconnected the battery charger the amperage read was just over 1 amp and stable with it dropping .1 amp at a time.
Clearly there is a relay, etc putting on a varying load but how the clicking continues is beyond me with the 12v power source removed unless there is a cap or something holding a charge at this time.
It sounds like it is coming from mid engine (alternator or to the left of the alternator). When I go around to the right side of the engine (pass. side) the sound is very faint. The battery charger was sitting over the center of the radiator and the clicking seemed to be coming from that location but my hearing is shot which does not help with trouble shooting.
Anyone ever experienced something like this with a GM truck of this era? Thanks for any thoughts. I now think the battery is NOT the issue since it is out of the loop and the clicking continues.
